Comparison of Power Line Filter Orientations

There are nearly no electronic products nowadays that can comply with the conducted emission regulatory requirements without the use of some form of filter. In this thesis research is performed on an one-stage power line filter, of which was observed that changing the installation orientation, could influence the filter characteristic. Simulations are used to analyze the power line filter itself, and investigate the reason of changing filtering behaviors by different orientations. Furthermore, different measurements are performed with different switched mode power supplies, to verify the simulation results.
